I love Proxmox as a virtual server manager - I can't imagine running anything else as a base for a homelab. Free, powerful, VMs or CTs operating quickly, graphical shell for administration, well documented and used, ZFS is a first class citizen.

I've kind of wanted to build a three node cluster with some low end stuff to expand my knowledge of it. Now they have a datacenter controller. I'd need to build twice the nodes.

Question: Does anyone know large businesses that utilize proxmox for datacenter operations?
